LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 270,722, dated January 16, 1883.

' Application filed November3, 1882. (No model.)

To all whom it may concern Be it known that I, LEWIS J. ATWOOD, of Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Lamp-Burners, of

which the following is a specification.

My invention relates to burners in which the wick-raising ratchets are inclosed within the base of the burner by means of what has been IO vtermed a ratchet-cap.

The invention consists in a method of combining the base and ratchet-cap with the body of the burner, and of attaching the chimneyholding springs to the ratchet-cap, whereby I dispense with rivets and solder; also in novel combinations of parts hereinafter described and claimed.

1n the accompanying drawings, Figure lrepresents an inverted plan of a two-wick burner embodying my invention. Fig.2represents a. vertical section thereof in the plane of the dotted line at m, Fig. 1. .Fig. 3 represents a similar section on the plane of the dotted line yy, Fig. 1; and Fig. 4 represents a detailview 2 5 illustrating the manner of securing the chimney-holding springs in place.

Similar letters of reference designate corresponding parts in all the figures.

A designates the burner-base, in which the wickraising ratchets a are placed, and which has an external screw-thread, b, providing for the attachment of the burner to alamp-collar. The wick-raising ratchets a are actuated in the usual way by means of ratchet-spindles e.

5 B designates the ratchet-cap, which covers the baseA; and O 0 designate the two-wick tubes, which extend upward through the airdistributerD; and E designates the cone or deflector, provided with two flame-slots, d.- The air-distributer Dis here represented as formed integral with the body E of the burner, and said body is supported upon arms, 6, extending from the base A. The arms 6 are formed integral with and project radially from the ratch- 5 et-cap B. They extend horizontally from the ratchet-cap, and are then bent upward, forming upright portions 0, and the body F has a horizontal shoulder or flange, F, having in it slots or holesf. The points a of the arm portions 6 are inserted through the holes oropen- 5o ingsf, and are bent over or clinched on the shoulder F, as seen clearly in Fig. 3. The ratchet-cap B is provided between the arms 6 with lips g, which are turned under the edge of the ratchet-case A, as shown in Figs. 1 and 2, and serve to secure the cap B to the base A. The space between the ratchet-cap B and the body F of the burner is closed by a perforated lower air-distributer, F, the lower edge of which rests upon the ratchet-cap and the upper edge of which is slipped into the body F.

G designates the chimney-holding springs, which are of usual form, and the lower ends of which extend horizontally inward.

The arms 6 have side lips, c ,which are bent up into tubular form, as shown best in Fig. 4, which representsa transverse section through one of the arms. The tubular portions or lips e are closed down upon or around the horizontally-extending end portions of the springs G, and the latter are thereby secured firmlyin place.

It will be seen that by my invention I provide for securing the body of the burner to the arms 6, and for securing the chimney-holding springs without solder or rivets, which is of importance in the manufacture of burners.

What I claim as myinvention, and desire to secure by Letters Patent, is- I 1. The combination of the base A, the ratch- 8o et cap B, provided with the integral arms 0, having the upwardly-extending portions c, and the body F, provided with slots or holesf, through which the points of the arms 0 e are inserted and then clinched, substantially as described.

2. The combination of the baseA and the ratchet-cap B, united by folding one over the edge of the other, the ratchet-cap being provided with integral arms 0, extending beyond 9:) said base, and the'chimney-holding springs attached directly to and supported by said arms, substantially as herein described,

3. The combination of the body F, the base A, the ratchet-cap B, provided with the integral arms 6, connected with the body and I having side lips, c and the chimney-holding the arms a c are inserted and clinched,the airspriugs G, over which the lips c are closed, distributer D, and the cone or deflector E, all 10 substantially as described. substantially as described.

4. The combination of the two wick-tubes C, the base A, the ratchets a, and their spin-' dles c, the ratchet-cap B, provided with the 1 Witnesses: integral arms a e, the body F, provided with W'. S. A'IWOOD, slots or holesf, through which the points of A. E. FOGG.
